Abstract

L'invention concerne un procédé et un dispositif permettant d'étendre le champ d'application des techniques de mesure de la corrosion fondées sur la méthode de la signature du champ à une gamme plus large de situations. L'invention s'adresse en particulier aux situations dans lesquelles l'emplacement faisant l'objet d'une exploration présente une corrosion préexistante. Le procédé décrit permet de détecter la corrosion dans un emplacement donné, et consiste à prendre une unité permettant le montage d'au moins deux contacts électriques, à appliquer cette unité de montage sur une réplique de l'emplacement exempte de corrosion, à mesurer la tension entre ces contacts électriques, à une ou à plusieurs reprises, les contacts électriques se trouvant en contact avec la réplique de l'emplacement devant être exploré, à appliquer l'unité de montage sur l'emplacement risquant de présenter une corrosion, à mesurer la tension et/ou la variation de tension entre les contacts électriques appliqués sur l'emplacement exploré, à faire passer un courant électrique à travers la réplique de l'emplacement et à travers l'emplacement exploré au moment de la mesure de la tension. Le courant est fourni par une source donnée pour les différentes mesures de tension, la mesure relevée dans l'emplacement de la réplique définit les caractéristiques propres à un emplacement exempt de corrosion, et les mesures de tension relevées dans l'emplacement indiquent l'étendue de la corrosion telle qu'elle se présente au moment de la première mesure de tension relevée dans l'emplacement et/ou indiquent la progression de la corrosion entre le moment de la première mesure et une ou plusieurs mesures de tension ultérieures relevées dans cet emplacement.
